John Hamilton McWhorter V (born 1965) is an American linguist and political commentator.[1] He is the author of a number of books on language and on race relations. His research specialties are how creole languages form and how language grammars change as the result of sociohistorical phenomena.

McWhorter is the author of the courses entitled "The Story of Human Language, "Understanding Linguistics: The Science of Language," and "Myths, Lies and Half-Truths About English Usage" for The Teaching Company. His 2003 Authentically Black has been interview-reviewed on booknotes.org, and he has also been interviewed on CSPAN's Book Notes In Depth series.[2]

Much of his academic work has concerned creole languages and their relationship to other ones, often focusing on the Surinam creole language Saramaccan. His work has expanded to a general investigation of how adults acquiring a language "undoes" much of the complexity and irregularity that human language otherwise inevitably wends into, to varying degrees of which creoles are simply an extreme. This includes Mandarin Chinese, Persian, the modern colloquial dialects of Arabic, Swahili, and Indonesian, as well as English. He has outlined these ideas in academic format in Language Interrupted and Linguistic Simplicity and Complexity, and for the general public in What Language Is and, on English, Our Magnificent Bastard Tongue.

McWhorter has also been a proponent of a theory that various languages on the island of Flores underwent transformation due to aggressive migrations from the nearby island of Sulawesi, and has joined scholars who document that English was profoundly influenced by the Celtic languages spoken by peoples encountered by Germanic invaders of Britain. He has also written various pieces for the media arguing that colloquial constructions such as the modern uses of "like" and "totally," and nonstandard speech in general, be considered alternate renditions of English rather than degraded ones.

McWhorter characterizes himself as "a cranky liberal Democrat". In support of this description, he states that while he "disagree[s] sustainedly with many of the tenets of the Civil Rights orthodoxy," he also "supports Barack Obama, reviles the War on Drugs, supports gay marriage, never voted for George Bush and writes of Black English as coherent speech". McWhorter additionally notes that the conservative Manhattan Institute, for which he works, "has always been hospitable to Democrats".[3] Regardless, McWhorter has criticized left-wing and activist educators in particular, such as Paulo Freire and Jonathan Kozol.[4] One author identifies McWhorter as a radical centrist thinker.[5]
